Hello,

how can all Parameters? i mean see by name like design script is doing it `x.Parameters[0]`

```auto
import clr
import sys
sys.path.append('C:\Program Files (x86)\IronPython 2.7\Lib')
import System
from System import Array
from System.Collections.Generic import *
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *
clr.AddReference("RevitNodes")
import Revit
clr.ImportExtensions(Revit.Elements)
clr.ImportExtensions(Revit.GeometryConversion)
clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager 
from RevitServices.Transactions import TransactionManager 

clr.AddReference("RevitAPI")
clr.AddReference("RevitAPIUI")

import Autodesk 
from Autodesk.Revit.DB import *
from Autodesk.Revit.UI import *

doc = DocumentManager.Instance.CurrentDBDocument
uiapp = DocumentManager.Instance.CurrentUIApplication 
app = uiapp.Application 
uidoc = uiapp.ActiveUIDocument

#Boilerplate Code
my_element = UnwrapElement(IN[0])
element_parameters = my_element.Parameters
OUT = element_parameters

```

f.e. when i want to see also the values and object type

Have i to do it parameter by parameter or is it possible to get all in one ?

The API method returns the parameter elements, which is what you’re seeing. In order to see the parameter name and/or value you’ll have to query them individually. The name you should be able to get just by `param.Name`. The values can be a little tricky because each parameter will be a different type and therefore require a different `As[Type]` method to return a “legible” value.

Look at what’s available from the `Parameter` class and it should make more sense.

Well you’d just use a loop, but yes. You have to go through each parameter to get it’s name and value individually. Same as looping through each element to get its list of parameters.

@Nick_Boyts

```auto
my_element = UnwrapElement(IN[0])
element_parameters = my_element.Parameters
IfcGuid = my_element.LookupParameter("IfcGUID")
parameter_value = IfcGuid.AsString()
OUT = "IfcGUID: " + parameter_value

```

same issues with IsInstance …

I don’t follow. Is that not what you’re after? The parameter name and it’s value?

Take a look at the members available to `Parameter` elements in the link I sent you. I believe there are a couple of ways to get this information depending on what version of Revit you’re using and how you want to get it.

Just to clarify here, the x.Parameters[0] in design script is actually calling a method on the elements that is returning the Name and Value. The my\_element.Parameters in your python is returning a list of Revit DB parameter elements that then need to be queried as @Nick_Boyts indicated. These two “Parameters” are not the same.
